Welcome to the FRACTULATOR. John Mahoney's personal foray into a command line fraction calculator. Yes, he could have used the built in Python fraction and greatest common denominator / least common multiple functionality but that felt like cheating.
The fractulator is designed to be a simple tool to use, and it is very much so if you follow a few simple rules.
- Fractulator supports Python 3.6-3.8
- First of all, make sure you
chmod +x fractulator.pyto make it executable. - In order to avoid having to escape all of your
*characters, runset -fbefore using the tool
-
Fractulator makes it easy to run command line fraction operations.
-
The following operations are supported:
+(Addition)-(Subtraction)*(Multiplication)/(Divison)
-
Here is an example:
./fractulator.py 6/3 + 14/2 * 19/17- Examples with
*assume you have runset -fbeforehand
-
Fractulator supports whole numbers and mixed numbers as well:
./fractulator.py 3 * 2_1/4- Syntax for a mixed number is
whole_numerator/denominator
-
When dealing with negative fractions, put the minus sign as the first character in the fraction to avoid parsing errors:
./fractulator.py -4/3 + -2_5/6
-
The output will be a whole number, mixed number, or fraction depending on what the result simplifies to
./fractulator.py 6/3 + 14/2 * 19outputs135./fractulator.py 16/17 * 18/19outputs288/323./fractulator.py 16/17 + 18/19outputs1_287/323
-
When an invalid input is supplied, you will receive the error reason in the output and the help text will be displayed
./fractulator.py 16/17 @ 18/19
Invalid input: 16/17 @ 18/19, @ is not a valid operator./fractulator.py 16/17 * 18q/19
Invalid fraction input: 18q/19./fractulator.py 16/17 * 18/19 +
Invalid input: 16/17 * 18/19 +, incorrect number of operands
-
Have fun with fraculator! All of the methods are well documented so if you find yourself needing a non-standard fraction library for Python go right ahead and do as you please with it!
Thank you!
